Abstract

A motor vehicle lamp assembly (10) having a light source (12) for emitting light and an enclosure having a two light transmissive portions (16) for transmitting light from the light source to the illumination zones. The enclosure is affixed with a material (32, 34, 36) which covers the light transmissive portion. The material (32, 34, 36) is electrically energized to alter an amount of light transmitted from the source to the illumination zones. A drive circuit (30) electrically coupled to the material (32, 34, 36) energizes the material to control a light output from the lamp assembly. The lamp assembly can simultaneously provide light in the direction of travel of the vehicle along with cornering lighting and turn signal function. The lamp assembly also includes a rear-projection lamp incorporating an optic lens (16). In addition, the assembly is configured to provide for various head-lamp functions including an advanced front lighting system.
